如何访问媒体库

Question

我正在尝试上传图像，但首先我必须访问媒体库，但是我的代码不正确，更新的代码可以解决此错误？

类型'SignUpViewController'没有成员'handleSelectProfileImageView'

        let tapGesture =   UITapGestureRecognizer(target: self, action: #selector(SIGNUPViewController.handleSelectProfileImageView))
        ProfileImage.addGestureRecognizer(tapGesture)
        ProfileImage.isUserInteractionEnabled = true
}
    @objc func handleSelectProfileImageView () {

@IBAction func profileImageBtnAction(_ sender: Any) {
    let alert:UIAlertController=UIAlertController(title: "Choose Image", message: nil, preferredStyle: UIAlertController.Style.actionSheet)
    let cameraAction = UIAlertAction(title: "Camera", style: UIAlertAction.Style.default)
    {
        UIAlertAction in
        self.openCamera()
    }
    let gallaryAction = UIAlertAction(title: "Gallery", style: UIAlertAction.Style.default)
    {
        UIAlertAction in
        self.openGallary()
    }
    let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.cancel)
    {
        UIAlertAction in
    }
    // Add the actions
    picker.delegate = self
    alert.addAction(cameraAction)
    alert.addAction(gallaryAction)
    alert.addAction(cancelAction)
    self.present(alert, animated: true, completion: nil)
}
func openCamera() {
    if UIImagePickerController.isSourceTypeAvailable(.camera){
        picker.allowsEditing = false
        picker.sourceType = UIImagePickerController.SourceType.camera
        present(picker, animated: true, completion: nil)
    }else{
        print("Simulator has no camera! So please run in real device which has camera")
    }
}
func openGallary()
{
    picker.allowsEditing = false
    picker.sourceType = UIImagePickerController.SourceType.photoLibrary
    present(picker, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    chosenImage = (info[UIImagePickerController.InfoKey.originalImage] as? UIImage)!
    profileImageview.image = chosenImage
    profileImageview.image = self.resizeImage(chosenImage)
    let date = Date()
    let formatter = DateFormatter()
    formatter.dateFormat = "dd-MM-YYYY hh:mm:ss"
    let dateExtension = formatter.string(from: date)
    let fileManager = FileManager.default
    let paths = (NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as NSString).appendingPathComponent(dateExtension).appending(".png")
    print(paths)
    imagedata = chosenImage.jpegData(compressionQuality: 0.5)
    fileManager.createFile(atPath: paths as String, contents: imagedata, attributes: nil)
    profileImageview.layer.cornerRadius = profileImageview.frame.width/2
    profileImageview.layer.masksToBounds = true
    dismiss(animated: true, completion: nil)
}
//What to do if the image picker cancels.
func imagePickerControllerDidCancel(_ picker: UIImagePickerController) {
    dismiss(animated: true, completion: nil)
}
Hope this will help your
